This seems counterintuitive but taking advantage of online grocery delivery and ordering schemes can save you money.

Modern stores are sophisticated marketing machines designed to make you buy as much as possible – so the less time you spend in them, the less money you will spend. When you order online, you can get just the stuff on your list, and there will be no incentive for impulse buying.

Details of the partnership were not available but it would presumably involve E. Leclerc accepting Amazon returns and possibly letting customers pick up Amazon orders in its stores. Another possibility is that customers might be able to order groceries from E. Leclerc through Amazon. Amazon recently entered into a similar arrangement with the ailing American department store chain Kohl’s (NYSE: KSS).

The privately-held E. Leclerc is France’s largest supermarket with 21.1% of the nation’s grocery market in April 2017, Statista reported. There were unsubstantiated rumors that Amazon might attempt to buy France’s second largest grocer Carrefour (OTC: CARR). Carrefour currently controls 20.9% of the French grocery market.

Walmart (NYSE: WMT) and Alphabet (NASDAQ: GOOG) have opened a major new front against Amazon (NASDAQ: AMZN) in the online retail wars.

Walmart products will soon be available through Alphabet’s (NASDAQ: GOOGL) online delivery solution Google Express, The New York Times reported. That means customers will be able to order stuff through Google shopping. It also means the merchandise they order will be delivered by Google’s branded vehicles.

It looks as if Walmart is actually beating Amazon in the delivery wars.

The discount giant has expanded its same-day service which was only available in Tampa and Phoenix to those cities, CNBC reported. Walmart customers in Denver are able to get orders delivered by Lyft, the article did not say if that service will be expanded.

Netflix loses money like crazy but it has built up a global platform for delivery of digital products. A danger is that Netflix might start selling products like video games, software, insurance, or financial services in addition to video entertainment. Another is that Netflix might team up with a retailer to start selling goods through its platform. A grave danger for Amazon would be Walmart or Alibaba buying Netflix and offering a Prime type delivery and entertainment option through it.

Walmart (NYSE: WMT) wants to turn every cashier, stocker and assistant manager in its stores into a delivery person.

A new program would pay employees to drop packages off at customers’ homes or business after they leave work, The Washington Post reported. The delivery initiative is already being tested at Walmart stores in New Jersey and Arkansas, Walmart.com CEO Marc Lore told reporters.

The same-day delivery war will be won by the company willing to stick it out, invest money, and spend several years slowly building up and rolling out its service. In that time, we’re liable to see consolidation and alliances Walmart or Amazon.com teaming up with Google Express, or Google contracting with Kroger or Uber to provide deliveries.
